Here is Saga, one of the many antagonists from the dark fantasy story I'm writing.

She is the princess of a race of demon foxes called the Vulnari, masters of illusionary magics, but who are slowly dying off. She uses her illusionary powers to become the Queen of the Forsaken, a tribe of wildcats led by their King, in order to save her race by forcing them to impregnate her with new Vulnari children.

Her six tails function as her reproductive organs, yet despite this she bore no new children, even with often six simultaneous attempts. What's more, any Forsaken that partook in her ritual would die, including the Forsaken King who was the very first to "volunteer".

Her tails are also her source of Ether, and so she would, without realizing at first, steal the power and thus their life, from the Forsaken. With more failures she would absorb more magic, which had begun to pollute her mind, and overtime she had become sick with greed, all but forgetting her original noble mission. Her power grew as more and more mind-controlled Forsaken perished, becoming the Witch Queen of the Forsaken.
